I have a little giant 9200 incubator with a egg turner in it. It holds a total of 42 eggs. I just finished a hatch of 36 eggs of which only 10 hatched. I followed the instructions very closely, but something went wrong. No bantams eggs hatched and less than half my brown eggs hatched. I made sure the water rings were full at the start of lockdown, left them alone and they started hatching on time. When I took out the first 7 I noticed the water rings were nearly dry, so I refilled them. I took both vent plugs out at the start of hatch. Only three more hatched. I had three that started pipping, but died before they hatched. Several fully developed chicks were in the eggs. What did I do wrong. The temp was a constant 100.
